The 11 Layers Kiya Aogami Utility 140mm is a handcrafted Japanese utility knife that combines over 230 years of knife-making heritage with exceptional cutting performance. Produced for Kiya Hamono, one of Japan’s most prestigious knife retailers founded in 1792, this versatile knife is forged by skilled artisan blacksmiths to meet the exacting standards that have made Kiya a benchmark for premium Japanese kitchen knives.
At its core is Aogami #2 (Blue Paper Steel), a premium high-carbon steel renowned for its remarkable edge retention, toughness and ability to achieve an exceptionally sharp cutting edge. Hardened to approximately 63 ±1 HRC, the blade delivers outstanding cutting performance while remaining easy to resharpen throughout its lifetime.
The blade features a traditional 11-layer construction, with a hard Aogami #2 steel core clad in multiple layers of softer steel for improved durability and strength. Finished with a classic Kurouchi (black forged) finish, each knife displays its own unique handcrafted character while providing a degree of protection against oxidation.
The slim utility blade is designed for precision and versatility, making it ideal for trimming vegetables, slicing fruit, preparing meat and fish, carving small joints and detailed kitchen tasks. Its narrow profile reduces food sticking, allowing for smoother, more precise cuts through fatty, oily and starchy ingredients.
Finished with an elegant rosewood handle, the knife offers excellent balance, comfort and control for extended use. As a high-carbon steel knife, the exposed cutting edge will naturally develop a protective patina over time and requires appropriate care to maintain its outstanding performance.
Combining traditional Japanese craftsmanship with premium materials, the 11 Layers Kiya Aogami Utility 140mm is an indispensable everyday knife for both professional chefs and passionate home cooks.
The shape is basically a small Sujihiki or slicing knife. As the name suggests it is a multi-function knife used for the preparation of vegetables and precise cutting of meat and fish. The slim profile presents a smaller area to fatty, oily, and starchy foods where a wider blade would create a stronger vacuum and ‘stick’ more to the food.
Function – Multipurpose for preparing all food groups. A favourite knife of many home cooks who are uncomfortable with large blades.
Normal length – 150mm
Tip: This knife is also used for carving petite roasts, filleting and skinning fish as well as careful dissection of poultry without hitting bones. An extremely useful size for any kitchen.
